Grayscaling a bitonal image
Posted: Thu Nov 29, 2007 10:07 pm
Hi,
I have a set of bitonal images (TIFF). I would like to send them to the browser. For that, I can convert them into GIF (or PNG). I am using ASP.NET / C#.
This works properly with GDI+ (No need for your ActiveX control)
Now, what I would like to achieve is grayscaling those images on-the-fly so the look better in the browser. I know this is possible (a lot of software do it, for example Windows Picture & Fax Viewer)
Do you think this would be possible using GdPicture ?
I tried the SetGrayScale method but obviously this one is to grayscale colored images only ...
Any idea ?
Thanks
Guillaume
